Hi,

I'm using 3rd-party audio service in my app, it has a capsuled audio recorder instance, so it conflicts with Horizon, how can I use Horizon for this situation?

Thanks!

Hey,

Thanks for all of your hard work on this fantastic library. I've had issues getting the library to run on the emulator due to detection of the device's open gl version.

    private void initView(GLSurfaceView glSurfaceView, @ColorInt int backgroundColor) {
        // check if the system supports opengl es 2.0.
        Context context = glSurfaceView.getContext();
        final ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        final ConfigurationInfo configurationInfo = activityManager.getDeviceConfigurationInfo();
        final boolean supportsEs2 = configurationInfo.reqGlEsVersion >= 0x20000;

        if (supportsEs2) {
            // Request an OpenGL ES 2.0 compatible context.
            glSurfaceView.setEGLContextClientVersion(2);

            // Set the renderer to our demo renderer, defined below.
            mRenderer = new BezierRenderer(glSurfaceView, backgroundColor);
            glSurfaceView.setRenderer(mRenderer);
            glSurfaceView.setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);
        } else {
            throw new UnsupportedOperationException();
        }
    }

The line final boolean supportsEs2 = configurationInfo.reqGlEsVersion >= 0x20000; always returns false and it appears that my emulator thinks that its opengl version is 0.0. Is this just a limitation of testing libraries dependent on opengl in general, or is there something I can do to make this work properly?

So far, I've gone into the emulator's settings and set OpenGL ES Render to Desktop native OpenGL and OpenGL ES API Level to Host Maximum.

When I add the dependency compile 'com.yalantis:eqwaves:1.0.1' to my gradle the sync process ends with the error: "manifest merger failed with multiple errors, see logs" with no further explanation on the logs.

Hi. I have a LG G2 with Cyanogen 12.1 installed.. The render works by 0.5-1 second and freezes. On my another device, Motorola G2, works fine. is it a problem with Cyanogen or with the library?

I tried my luck with Visualizer and sending the byte[] data from Visualizer.setDataCaptureListener but the vizualization is not syncronized.

I tried both Waveformdata and FFTData

Does Horizon support sound recorded with MediaRecorder (separate activity) and then loaded in a fragment using BufferedInputStream from a file?

This is how I load it in but I get weird results, it initializes the wave and then the wave disappears after a second.

                    int size = (int) audio_file.length();
                    byte[] bytes = new byte[size];
                    BufferedInputStream buf = new BufferedInputStream(new FileInputStream(audio_file));
                    buf.read(bytes, 0, bytes.length);
                    buf.close();


                    if( isRecording){
                        mHorizon.updateView(bytes);
                    }

Any tips would be awesome!

Thank you for your hard work making this excellent library. According to the AudioRecord documentation, reading byte[]s from a buffer is only compatible with ENCODING_PCM_8BIT.

Reads audio data from the audio hardware for recording into a byte array. The format specified in the AudioRecord constructor should be ENCODING_PCM_8BIT to correspond to the data in the array.

https://developer.android.com/reference/android/media/AudioRecord.html#read(byte[], int, int)

I see that in your example you are indeed using reading a byte[] from the AudioRecord buffer, yet you're also specifying ENCODING_PCM_8BIT. Is there any way to use Horizon with a short[], or should we continue to use byte[] and specify ENCODING_PCM_8BIT?

I want the wave to respond to human speech. Is there some way it could ignore background noise like the sound of fan or ticking of clock, because it keeps plotting waves always and never comes down to a straight line?
